Greetings to all of my fellow cyclists! Today, I’m following up from my most recent post on barthaynes.com titled “How to Troubleshoot Your Bike.” Upon publishing this article, a less experienced cyclist friend of mine said, “That’s great, Bart, but I don’t know where half of those things are on my bike!”

In order to help those of you out who don’t know bicycle parts as well or need a bit of a refresher regarding the anatomy of your bike, this post is for you. I scoured the Internet to find some excellent diagrams for you to study. I’ve included multiple photos for quality, thoroughness, and types of bikes.

In between these diagrams, I’m going to include some definitions of bicycle parts that might seem complicated to the amateur bicyclist. My hope is that this post will teach you how to identify the parts of your bicycle so that you can discuss cycling intelligently and also know how to describe problems if you run into any difficulties in the future.
